Set owner in image module

Previously the owner field was not set by module
`cloud.openstack.image`, although it is specified as a module parameter.
The usual approach in `ansible-collections-openstack` is to accept both
names and IDs when referencing openstack resources.
Therefore this commit follows the approach taken by
`python-openstackclient` in [1] and introduces a `project` and a
`project_domain` parameter to identify projects by name or ID and
assign the ID to the `owner` attribute of the image.
The `owner` parameter is left as an alias to `project` in the module.
